For this questionenter image description here

I know something the usage about “diag” function, when n increases, does the matrix looks like a diagonal matrix that other pivots fill with zeros? Does this matrix can be constructed by simply calling the "diag" function?

This can be done by creating three matrices using diag, one for the diagonal, superdiagonal and subdiagonal then summing the three together. – JessicaK Apr 06 '20 at 14:53
So the required matrix should be three 100-row matrix summed up? – Jerry Wong Apr 06 '20 at 15:04
